Swedish blog Gossip_dance, states,
"Kristen Stewart and Taylor Lautner will make a quick stop in Stockholm, Sweden during their Europe Eclipse Promo Tour.

A press conference for Scandinavian media will be held on June 21st.

As for now we have no more information on if there is any event planned too. But we will update you with the latest info as soon as we have it.

Other confirmed stops are Rome and Berlin.

(as it seems Rob will not attend any Europe promo). Thank you Nordisk Film."

I hope to get more details on this as the story progresses.I am sure this is a part of their European promo, we will get confirmation of their other stops soon. Don't be hard on Rob and Summit. Rob is on a schedule for a big film and he can't rearrange the production schedule around his own. At least he is already in LA for the Eclipse press junket on June 13-14.
